According to research conducted by ridley (1999), how could individuals like adolf hitler, serial killer ted bundy, and oklahoma city bomber timothy mcveigh commit such acts according to the "nature versus nurture" debate?

Their behaviors are the result of the interaction of nature and nurture. The theory of nature versus the theory of parenting is based on the theory that the personality of an individual is more influenced by the structure of their genetics or the environment in which they have grown. The theory is used to find the cause of an individual's actions. Given that these individuals commit these acts because of a brain situation that makes them a person with a type of disorder or mental illness that makes them different in their behavior.
